About the NY NOAA data

This dashboard uses the ny_noaa dataset from the p8105.datasets package. The data come from the National Oceanic and Atmospheric Association (NOAA) of the National Centers for Environmental Information (NCEI) database.

For smooth viewing, the scatter plot shows a random sample of up to 20,000 days. The box plot and bar chart use the filtered data or monthly counts.

Figure 1: Temperature

What it shows: This plot displays the relationship between daily minimum and maximum temperatures, covering a range of weather conditions across New York between 2000 - 2010. There is a clear upward pattern, meaning that warm days usually follow warm nights. The yellow and green points in the upper-right area occur during summer, while the purple and blue points in the lower-left area occur in fall or winter, when overall temperatures are lower.

Figure 2: Snowfall

What it shows: How daily snowfall changes across the months of the year. Winter months have more snowfall and more variation, while summer shows almost none.

Figure 3: Precipitation

What it shows: The number of days with precipitation in each month and which parts of the year are wetter or drier in New York. Taller bars mean that month had more wet days, while shorter bars mean fewer. The seasonal pattern is visible: late spring through winter generally has more wet days than midsummer.
